Abstract:The water leakage in the urban areas causes a continuous rise in the water table, with harmful effects. An experimental drainage system, based on horizontal well technology, was designed and implemented in a populated area. Groundwater flow modeling was used to assess the hydrodynamic efficiency of the system through drain conductance parameter estimation.
Keywords:Urban area  Water table rise  Gravitational drainage system  Horizontal wells  Drain conductance  Hydrodynamic efficiency
